Sphinxes

There could be these little temple structures with a sphinx sitting in front of the entrance and as long as the Sphinx is three riddles are not completed the area around the Sphinx cannot be broken and the Sphinx cannot move out of the way the Sphinx is riddles would work like this you would press use on a sphinx and it would give you an ancient tablet which would have a riddle on it then after you read the riddle you have to get the block or item the riddle was hinting at then you give the Sphinx both the tablet and the item and if you get it correctly it's eyes would flash green and then it would give you another tablet once you complete three riddles the Sphinx would move over to the side and you would be able to go down into the temple and collect some really good loot but if you get it wrong their eyes would flash red and you would have to answer a different three riddles and you would possibly have to wait until the next Minecraft day to try to answer a riddle again. I think that this idea could add a little bit more to the deserts of Minecraft and I think it would be a really cool addition that would just make people who like to solve puzzles and adventure like the game just that much better. Thank you for your time, listening to my idea, making Minecraft better everyday, and I hope you have a good day!
